Four Tools Hidden Inside One Aluminum Pen Light

THE ARTICLE – The pen light category has not been the focus of innovation. Many options are cheap plastic tubes that fit in a doctor’s coat pocket and do one thing. Olight looked at that space and decided that the pen light should be a pen, a flashlight, a laser pointer, and an emergency signal all at the same time. The O’Pen 3 is their attempt to make that work without turning it into a gadget that’s too busy to use.

At 6.1 inches tall and half an inch wide, the O’Pen 3 doesn’t look like it’s hiding anything. It writes, sticks in a pocket, and can pass for a nice aluminum pen at a meeting without asking questions. The tone of the four instruments only becomes apparent when you start clicking on the modes built into the clip and body.

120 lumens from the pen clip

The white light sits on the clip itself, which is clever placement that keeps the beam at an angle when the pen is attached to a pocket or notebook. Coming in at 120 lumens, it won’t replace a dedicated lamp but handles close tasks like reading a menu in a dim restaurant or finding a keyhole at night without a problem.

Where things get really interesting is the red light system. The Olight is designed with a two-stage red mode designed to preserve night vision, the kind of feature that usually appears in dedicated tactical lights rather than pen-sized tools. There’s also a red SOS mode for emergencies, and a soft tip that illuminates the writing surface when you’re working in the dark. The latter sounds good until you try to take notes during a presentation or fill out a form in a dimly lit room.

A green laser with two light levels

The Class 3R’s blue laser pointer is the feature that pulls most of the weight of the $79.99 price tag. Blue lasers are more visible than red ones in daylight and in large rooms, making them useful for presentations rather than just a fun addition. It’s the difference between a red dot that no one can find on the whiteboard and a bright green dot visible on the back row. With a pen flashlight this small, that kind of visibility is a huge advantage.

Olight has given the laser two levels of brightness, details that suggest they actually thought about how people use laser pointers in real situations. Full power works in large conference rooms and outdoor orientation. The low setting of the O’Pen 3 saves battery and reduces eye strain in small areas. For anyone who’s ever had to borrow an invisible red dot clicker during a meeting, the integrated green laser changes the equation of whether a pen light is worth the pocket space.

Pen light with hidden USB-C and meteor shower grip

Charging sits behind a hidden USB-C port that keeps the pen’s silhouette clean when it’s not plugged in. Olight says a full charge takes about an hour, fast enough that a break-out can get you through the day.

The hidden port is a little more important detail than it should be, because visible charging ports on EDC gear have a way of collecting pocket lint and looking worse every month. The body itself is machined aluminum with a slightly tapered frame that tapers towards the end.

Olight went with what they call a meteor-shower-inspired grip pattern, which translates to a layer of texture that provides traction without being aggressive enough to grip the fabric. It comes in Black, Wine Red, and Orange, with the first two specialist leanings and the third adding a bold option for anyone who wants their EDC gear to stand out. The spring-loaded clip handles pocket carry, and the overall construction feels closer to a mid-range aluminum pen than a writing flashlight.

The pen light for the EDC crowd

The EDC pen light spot is small but growing fast. The intersection between people who carry a good pen and people who carry a small flashlight is bigger than most companies think, and Olight places the O’Pen 3 squarely at that intersection.

At $79.99, it’s not a fixed purchase, but it replaces a standalone pen light, EDC pen, laser pointer, and emergency signal. For anyone who already owns multiple single-purpose tools, those calculations start working in the O’Pen 3’s favor very quickly.
